【摘要】：地震是全球造成人员伤亡和财产损失最大的自然灾害，目前的科技水平还不能对地震的发生进行准确的预测，也没有有效的措施可以防止地震的发生。减轻地震灾害根本途径是对工程进行合理的抗震设计，抗震规范是工程抗震设计的主要依据。中美欧都是全球地震频发的国家和地区，但由于美国和欧洲抗震规范较为完善，抗震设计方法较为合理，历次大地震造成的人员伤亡和财产损失均远低于我国。因此，本文系统对比中美欧抗震规范，指出中国规范抗震设计与美欧规范的差异，为我国的抗震研究和抗震设计提供参考，促进我国抗震规范的进一步完善，与国际抗震规范接轨。论文的主要工作和研究成果如下：（1）从抗震设防水准目标、抗震设计方法、场地类别、地震区划、抗震设计反应谱、重要性类别、重力荷载取值等方面对比中美欧规范的抗震设计基本规定，分析中美欧规范抗震设防思想和设计方法的的差异，并建立各规范在场地类别、地震动参数、重要性类别等方面的对应关系。（2）对比中美欧规范的底部剪力法和振型分解反应谱法的计算理论和计算方法，，并以具体的钢筋混凝土框架结构为例，通过底部剪力法和振型分解反应谱法计算其地震作用，直观比较中美欧规范地震作用。（3）从内力调整和构造措施两个方面对比中美欧规范钢筋混凝土框架结构抗震措施，比较中美欧规范钢筋混凝土框架结构的延性等级。（4）分别按照中美欧规范的相关规定完成某钢筋混凝土框架结构的抗震设计，直观对比中美欧规范钢筋混凝土框架结构的抗震设计结果。
[Abstract]:Earthquake is a natural disaster that causes the greatest casualties and property losses in the world. At present, the level of science and technology can not accurately predict the occurrence of earthquakes, and there are no effective measures to prevent the occurrence of earthquakes. The basic way to reduce earthquake disaster is to carry on the reasonable seismic design to the project, and the seismic code is the main basis of the seismic design of the project. China, the United States and Europe are the countries and regions with frequent earthquakes, but because of the perfect seismic code and the reasonable seismic design method in the United States and Europe, the casualties and property losses caused by the previous major earthquakes are far lower than those in China. Therefore, this paper systematically compares China, America and Europe seismic code, points out the difference between Chinese code and American and European code, provides reference for our country's seismic research and seismic design, and promotes the further improvement of our country's seismic code. In line with the international seismic code. The main work and research results are as follows: (1) from the seismic fortification level objectives, seismic design methods, site categories, seismic zoning, seismic design response spectrum, importance categories, Comparing with the basic rules of seismic design of the code of China, America and Europe, the difference of the seismic fortification thought and design method of the code of China, America and Europe are analyzed, and the parameters of ground motion of each code in the site category are established. The corresponding relation of importance category and so on. (2) comparing the calculation theory and calculation method of the bottom shear force method and the mode decomposition response spectrum method, and taking the concrete reinforced concrete frame structure as an example, the seismic action is calculated by the bottom shear force method and the mode decomposition response spectrum method. A direct comparison between China, the United States and the European normative earthquake action. (3) comparing the seismic measures of reinforced concrete frame structure between China, America and Europe, and comparing the ductility grade of reinforced concrete frame structure in the code of China, America and Europe from the aspects of internal force adjustment and construction measure. (4) the aseismic design of a reinforced concrete frame structure is completed according to the relevant regulations of the Central American and European codes, and the seismic design results of the reinforced concrete frame structure in the code of China, America and Europe are compared intuitively.
